, PROCESS OF MANUFACTURING GAS.

' mixture of mineral carbonates and organic sub.-.;inces, my object being to exclude as completely as possible all non-ignitible elements. such as nitrogen and oxygen, from the air, and to completely decompose the organic substance used in connection with the min- (l'ill carbonate or carbonates in such a mannor as to form staple ignitible gases from the carbon, oxygen and hydrogen contained in both the mineral carbonate and organic substances used, leaving as a residuum ash, minoral 0- id. metals and the non-volatile inorganic substances that may be contained in the mineral carbonate used. t

The drawing is a diagrammatic view of an apparatus adapted for carrying out my improved process, and, as shown, the ap ratus comprises a series of retorts, 1, 2 an 3, constructed of fire clay, or analogous material, arrangedin the usual manner in a furnace 4; and the ends of said retorts being normally closed by removable plates 5.

The forward ends of the retorts 1 and 2 are united by a tubular connect-ion 6, and in like manner the forward ends'of the retorts 2 and 3 are united by a tubular connection 7, and leading upwardly from the upper rear end of the retort 3 is a. discharge pi )e 8, which leads to a water seal or trap 9. leading froin the trap l) is a pipe 10, in which is located an exheuster 1i, and said pipe leads to a gasometer or storage tank 12.

In general operation, the mineral carbonate is broken to the desired size and then mixed with the organic substance which has been cut or ground to the desired size to form a close mixture with the mineral carbonate in such proportionsthat the carbon in the organic substance used is c urd to about ten )6! cent. (10%) by weightol the mineral carbonates used. A

The mineral carbonate used may be mag- Specification of Letters Patent.

t nesium carbonate, calcium carbonate, calcium t and magnesium carbonate, cupric carbonate, or cu prous carbonate, or any mineral carbon 5 ate which does not contain an objectionable volatile metal may be used.

The organic substance used may be dried vegetable matter, leaves, straw, corn stalks, saw dust, barks, or any dry organic sub-- stance containing hydrogen and carbon, or hydrogen, carbon and oxygen.

The mixed substance is placed in retorts 1, 2 and 3 until said retorts are about thre fourths full. are now closed air tight, and fire is built in the furnace, using as fuel coal, wood, oil, alcohol, or gas, as may be desired, and the temperature in the retorts is brought up to about 1200 degrees F., which temperature is maintained as near as possible until all the volatile matter has been expelled from the carbonate and the organic substance has been 'plisher in three or four hours.

During the decarbonization of the mineral carbonates in connection with an organic substance, the exhauster 11 is operated continuously so-as to remove the gases from the retorts 1, 2 and 3 as fast as generated, thereby hastening the operation, and at the same time preventing an excesspressure against the walls of said retorts. a

The gases generated in the retorts 1 and 2 are drawn through the tubular connections 6 and 7, to and through the retort3, and from thence said gases pass through the dis chargcpipe 8 into the trap or waterseal 9, and thence through pipe 10 to the gas holder and used asdesired. I

The object forpassing the gases generated in retorts 1 and 2 throu h retort 3, as 'described, is to utilize the. ot gases from reretort 3 equal to the heat in retorts land 2, retort 3 being located at a greater d stance decom osed into gas, which is-usually accom-' torts 1 and 2 to assist in keeping the heat in- By this method a more.
